It’s “true” in the sense that it could happen in theory, Google is (allegedly?) planning to use WEI for forcing people to see ads rather than China-firewalling the web; also, WEI was still under development last time I checked.
Whether the attesters that end up being universally trusted will poke around to check for VPNs is up for speculation, for now.
Even then, this is just an API for websites. If you use other means of communication, you’ll be fine.
